Bone Chill sounds perfect! I went to the pet store today, but no luck... I will have to go to another store. Thanks for the suggestion. I bought green beans and they are in the freezer now.
I bought Charlie a green frog with ropes as legs today, and lo and behold, he found his voice! He would not stop barking at it. The cutest thing. I shouldn't encourage the barking, but it was the first time I hear his voice..and angelic it is!
Pics are coming soon!!!
